910 Some MIPS machines can be configured for either little or big endian
5e83d430 911 byte order. These modes require different kernels and a different
3cb2fccc 912 Linux distribution. In general there is one preferred byteorder for a
5e83d430 913 particular system but some systems are just as commonly used in the
3dde6ad8 914 one or the other endianness.

1195 designed to be generic, i.e. Kernels compiled for R3000 CPUs will

1411 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1412 require workarounds. Without workarounds the system may hang
1413 unexpectedly. For more information please refer to the gas
1414 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1415
1416 Loongson 2F03 and later have fixed these issues and no workarounds
1417 are needed. The workarounds have no significant side effect on them
1418 but may decrease the performance of the system so this option should
1419 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1420 systems.

1723 This is a kernel model which is known a VSMP but lately has been

1725 Virtual SMP uses the processor's VPEs to implement virtual
1726 processors. In currently available configuration of the 34K processor
1727 this allows for a dual processor. Both processors will share the same
1728 primary caches; each will obtain the half of the TLB for it's own
1729 exclusive use. For a layman this model can be described as similar to
1730 what Intel calls Hyperthreading.

1750 On currently available 34K processors this means a Linux system will
1751 see up to 5 processors. The implementation of the SMTC kernel differs
1752 significantly from VSMP and cannot efficiently coexist in the same
1753 kernel binary so the choice between VSMP and SMTC is a compile time

1880 SmartMIPS is a extension of the MIPS32 architecture aimed at
1881 increased security at both hardware and software level for
1882 smartcards. Enabling this option will allow proper use of the
1883 SmartMIPS instructions by Linux applications. However a kernel with
1884 this option will not work on a MIPS core without SmartMIPS core. If
1885 you don't know you probably don't have SmartMIPS and should say N
1886 here.
